SPINDLE FOR SPINNING AND DOUBLING MACHINES.

Specification of Letters Patent.

Patented Feb. ME, 1911.

Application filed October 6, 1905. Serial No. 281,682.

To all whom "it may concern:

This invention relates to the spindles of spinning and doubling machineswhich are constructed with the concentric spindles one a cop spindleupon which the cop or bobbin is wound and the other a flier or guidespin dle carrying guides or presser arms to direct the yarn onto the copor bobbin.

The invention is designed with the object of driving the cop spindle atthe desired speed to wind up the cop thereon by direct frictionalcontact with the interior of flier or guide spindle and consists of theimprovements hereinafter described.

The invention will be fully described with reference to the accompanyingdrawings.

Figure 1. is an elevation of the flier. Fig. 2. is a sectional elevationof same. Fig. 3. is an elevation of foot of cop spindle showing dragmotion. Fig. l. is a plan of cop spindle and drag motion.

The cop spindle A upon which the cop is wound is solid and is supportedby a footstep bearing in the bottom rail, and passes through the socketd of the flier D supported by a bearing or collar B in the top rail C,one or both of which rails lift to form the cop.

The hollow flier D is mounted concentrically on the cop spindle A so asto revolve within the bearing or collar B carried by the top rail C. Itis provided with a whirl E by which it is driven by a cord or band atthe desired speed. Above the whirl extend the cup or flier with guideeyes (Z.

The flier is constructed with a hollow extension or sleeve d whichembraces the cop spindle A. The interior of the sleeve (Z is infrictional contact with the cop spindle A and the latter is directlydriven thereby at any speed not exceeding the speed of the flier. Thelong sleeve (5 projects into the interior of the collar B and rotateswithin it. The whirl E is mounted on an outer sleeve projecting downwardand covering the col lar B but not in contact with it.

At its lower end the cop spindle A is provided with a wharve or pulley Gto which a drag or brake band 9 is applied. The

drag band may be attached at one end to a spring H or supplied with aweight by which the tension can be increased or reduced to regulate thespeed at which the cop spindle shall rotate. The drag or brake may be ofany convenient form to retard the rotation of the spindle.

The flier is rotated at the desired speed by a band upon the whirl E andthe cop spindle A is rotated by the frictional contact of the interiorof the sleeve (Z. The drag or brake g is applied to the spindle A toreduce the speed below the speed of the flier so as to wind the yarnupon the bare spindle. When the yarn is being wound onto the largediameter of the cop the pull of the yarn at a greater leverage overcomessome of the resistance of the drag or brake and thereby rotates thespindle at the desired acceleration for winding on the greater diameter.

Vhat I claim as my invention and desire to protect by Letters Patentis 1. In a spindle for spinning and doubling, the combination with thecop spindle A and the flier of a long sleeve aflixed to the flier withthe interior of which the cop spindle A is in frictional contact, afixed collar B to support the flier, a sleeve attached to the flierextending around the fixed collar but out of contact therewith, and awhirl E thereon by which the flier and spindle are rotated,substantially as described.

2. In a spindle for spinning and doubling the combination of the copspindle A, the flier, a long sleeve aflixed to the flier the interior ofwhich is in frictional contact with the cop spindle, a collar B tosupport the flier, a sleeve attached to the flier extending around thefixed collar and a whirl E there on by which the flier and spindle arerotated and means by which the speed of the cop spindle is retarded inrelation to the flier by which it is driven substantially as described.

3. In a spindle for spinning and doubling the combination of the copspindle A, the flier, a long sleeve affixed to the flier the interior ofwhich is in frictional contact with the cop spindle, a collarB tosupport the flier, a sleeve extending over the fixed collar and.attached to the flier, and a whirl E thereon, by which the flier andspindle are rotated, a pulley G on the lower end of the cop spindle anda drag cord 9 held with the desired degree of tightness against thepulley substantially as described.

4. I11 a spindle for spinning and doubling the combination of the copspindle A, the flier, a long sleeve affixed to the flier the interior ofwhich is in frictional contact with 5 the cop spindle, a collar B tosupport the 10 and a drag cord 9 and a spring H with adjusting screw bywhich the desired degree of tension is applied to the pulley G sub?stantially as described and shown. 5

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
